struts2遇见的错误

1.The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servletfilter, which initializes the Struts dispatcher needed for this
tag.

出现此问题，在原配置下加上jsp过滤器。【还不知道为啥。】

<filter-mapping>

<filter-name>struts2</filter-name>

<url-pattern>*.jsp</url-pattern>

</filter-mapping>

2.java.lang.RuntimeException: Invalid action class configuration that references an unknown class named [AccountAction]；

Method "setRoleId" failed for object com.gather.bean.Rolelist@357bf9 [java.lang.NoSuchMethodException:

com.gather.bean.Rolelist.setRoleId([Ljava.lang.String;)]

可能性1：页面上的roleId字段前面多了一个空格, 删掉。

可能性2：struts配置文件里，Result返回值不对。改正。
